+DataLake-Handler MS
+==============
+
+**DataLake-Handler MS** is a software component of ONAP that can systematically persist the events from DMaaP into supported Big Data storage systems.
+It has a Admin UI, where a system administrator configures which Topics to be monitored, and to which data storage to store the data.
+It is also used to manage the settings of the storage and associated data analytics tool.
+The second part is the Feeder, which does the data transfer work and is horizontal scalable.
